AEM Startup Calibration and Application Notes for the 30-1510 EMS

[JP]

Aggressive as you want it to be. It is programmable.

The stock settings has a maximum ignition retard of 5 degrees and a maximum fuel increase of 10%. Check out your Knock Control Template in:

Setup | Sensors | Knock Sensor

JP, if I understand correctly, the dyno numbers you posted are from the startup caliberation on a stock SRT; my '05 is completely stock with the exception of the EMS. I followed the instructions , set the throttle, uploaded the base map but when I took it for a test run the car ran horrible, it was slow and boggy and only boosted around 5psi and when I opened up the throttle it took a really long time for the engine to even wind up. Did I miss something? and have others experienced this?

Something is not right. Give me a complete list of modifications to your SRT-4.

check that you didnt bump loose the Upper preasure pipe or the sensor the fits into it .. sounds like a boost leak.

JP, To the best of my knowledge my car is completely stock other than the EMS, And I don't think it is a boost leak because when I put it back to stock it boosted normally. When I put the EMS back in the problem is more than just low boost, the car has a boggy feel, when I step on the gas it takes forever for the engine to wind up, my AFR gauge reads really lean at Idle like in the 16's but I can smell tons of fuel pouring out the exhaust.  I bought the car used with 6k mile on it. May be somebody put some mods on that I can't see. I'll have someone more knowledgeable look it over and get back to you.  Thanks

which wideband are you using? it sounds like you are using the stock o2 sensoror another narrowband, if this is true did you calibrate Setup>sensors >oxygen sensor>O2 sensor #1>O2 sensor #1 cal table>table to emulate your sensor.. if you are using another wideband did you set o2 sensor gain to 1.0 .. it comes with a gain of 1.2something. which gauge are you using? how did you hook it up did you splice into the c2-31 on the wiring harness? did you leave the excess wire attached ( did you use a splice connector or did you really cut the wire and solder in and correctly weather proof the soldered connection ) if you left the excess it may not read correctly. It really sounds like your o2 sensor is not working correctly with the EMS and is dumping a ton of gas in. go to the back of the car while idling do you have black deposits forming inside the tail pipe .. have someone rev the gas while you are back there and put your hand infront of the driver side exhaust do you get what feels like sand hitting your hand? If do you have a plugged/ broken catalytic converter..

I've got the AEM Wide band UEGO controller, I think it didn't get hooked up right. It's obvilously beyond my scope of understanding so I made an appointment with an AEM factory tuner to get things straightened out.

make sure you uploaded the right map
